3.2 Installation
3.2.1 Site
All energy consumed by the centrifuge is converted into heat and emitted into the
ambient air. Therefore, sufficient ventilation is important. The air-ducts in the unit
must be open. Also, the centrifuge shouldn`t be positioned near radiators and
should not be directly exposed to sunshine.
A clearance of at least 30 cm around the centrifuge is necessary.
For normal operation the ambient temperature should not fall below 10
°
C and
not exceed 35
°
C. The max. humidity of air is 80 %. During transport from cold to
warmer places water will condensate inside the centrifuge. It is important that
there is enough time for drying before the centrifuge can be started again.
3.2.2 Connection/Fuse
The operating voltage on the name plate must correspond to the local supply
voltage!
SIGMA laboratory centrifuges are units of safety class I, DIN VDE 0700, and in-
clude a three wire power cord 2,5 m long with shockproof right angle plug. The
instrument has thermal fuses. In case of a disconnection through the thermal
fuses, allow a cool-down phase of two minutes, after which they could be
reactivated by a switch.
3.2.3 Fuses / Emergency Circuit Breaker on Site
The centrifuges must be protected typically with at least 16 A slow acting fuses.
An emergency circuit breaker to cut the power to the centrifuge in the event of a
malfunction is required on site. This switch should be located away from the
centrifuge, preferably outside the room where the centrifuge is used or at the exit
of this room.
